I sometimes see people write in #python
> isinstance(value, int) or isinstance(value, str)
although isinstance has been able to check for multiple types at once for as long as i remember, using.
> isinstance(value, (int, str))
so i refered someone to the official doc today https://docs.python.org/3/library/functions.html#isinstance
and realized it’s even better now, one can use union types
> isinstance(value, int | str)
Easy to miss that improvement if as me you’ve been using python for long enough you don’t look up docs.
